[fixes]
# (Default: true)
# Whether to disable the shutdown hook of log4j2 on dedicated servers.
# Enabling this also makes the JVM exit when the dedicated server is considered fully shut down.
# This option have no effect on client-side.
# We has historically been doing this, and this config option allows you to disable this behavior.
#
disableLoggingShutdownHook = "default"
# (Default: true) Enforces safe world random access.
# This feature detects unsafe off-thread world random access, helping to find the causes
# of mysterious "Accessing LegacyRandomSource from multiple threads" crash.
# The default behavior is to fail hard when such bad things happens.
# Disabling this option will replace this behavior with a warning.
#
# It is generally not recommended to disable this settings unless you know what you are doing
#
#
enforceSafeWorldRandomAccess = "default"
[noTickViewDistance]
# (Default: true) Whether to enable no-tick view distance
enabled = "default"
# (Default: 24) No-tick view distance max concurrent chunk loads
# Lower this for a better latency and higher this for a faster loading
maxConcurrentChunkLoads = "default"
# (Default: true) Whether to use compatibility mode to send chunks
# This may fix some mod compatibility issues
compatibilityMode = "default"
# (Default: true) Enable server-side support for extended render distance protocol (c2me:ext_render_distance_v1)
# This allows requesting render distances higher than 127 chunks from the server
#
# Requires Fabric API (currently available)
#
enableExtRenderDistanceProtocol = "default"
# (Default: false) Whether to ensure correct chunks within normal render distance
# This will send chunks twice increasing network load
ensureChunkCorrectness = "default"
[ioSystem]
# (Default: 8192) Soft limit for io worker nbt cache
chunkDataCacheSoftLimit = "default"
# (Default: 32678) Hard limit for io worker nbt cache
chunkDataCacheLimit = "default"
# (Default: false) EXPERIMENTAL FEATURE
# This replaces the way your chunks are saved.
# Please keep regular backups of your world if you are using this feature,
# and report any world issues you encounter with this feature to our GitHub.
#
# Whether to use the fast reduced allocation chunk serializer
# (may cause incompatibility with other mods)
#
gcFreeChunkSerializer = "default"
# (Default: true) Whether to use the optimized implementation of IO system
replaceImpl = "default"
[vanillaWorldGenOptimizations]
# (Default: true) Whether to use density function compiler to accelerate world generation
#
# Density function: https://minecraft.wiki/w/Density_function
#
# This functionality compiles density functions from world generation
# datapacks (including vanilla generation) to JVM bytecode to increase
# performance by allowing JVM JIT to better optimize the code
#
# Currently, all functions provided by vanilla are implemented.
# Chunk upgrades from pre-1.18 versions are not implemented and will
# fall back to the unoptimized version of density functions.
#
useDensityFunctionCompiler = "default"
# (Default: true) Whether to enable aquifer optimizations to accelerate overworld worldgen
# (may cause incompatibility with other mods)
optimizeAquifer = "default"
# (Default: true) Whether to enable End Biome Cache to accelerate The End worldgen
# This is no longer included in lithium-fabric
# (may cause incompatibility with other mods)
#
useEndBiomeCache = "default"
# (Default: true) Whether to enable StructureWeightSampler optimizations to accelerate world generation
#
optimizeStructureWeightSampler = "default"
[generalOptimizations]
# (Default: 100000) The task interval of mid-tick chunk tasks in nanoseconds (-1 to disable)
# Mid-tick chunk tasks is to execute chunk tasks during server tick loop
# to speed up chunk loading and generation
# This helps chunks loading and generating under high MSPT but may raise
# MSPT when chunks are loading or generating
#
# It is generally not recommended to adjust this value unless you know
# what you are doing
#
# Incompatible with Dimensional Threading (dimthread)
#
midTickChunkTasksInterval = "default"
[generalOptimizations.autoSave]
# (Default: ENHANCED) Defines how auto save should be handled
# VANILLA: Use vanilla auto-save behavior (auto-save performed every tick during ticking)
# ENHANCED: Use C2ME enhanced auto-save (auto-save performed when the server have spare time after ticking)
# PERIODIC: Use pre-1.18 vanilla auto-save behavior (auto-save performed every 6000 ticks during ticking)
#
# Please preserve quotes so this config don't break
#
mode = "default"
[chunkSystem]
# (Default: true) Whether to enable async serialization
#
asyncSerialization = "default"
# (Default: false) Whether to recover from errors when loading chunks
# This will cause errored chunk to be regenerated entirely, which may cause data loss
# Only applies when async chunk loading is enabled
#
recoverFromErrors = "default"
# (Default: true) Whether to allow POIs (Point of Interest) to be unloaded
# Unloaded POIs are reloaded on-demand or when the corresponding chunks are loaded again,
# which should not cause any behavior change
#
# Note:
# Vanilla never unloads POIs when chunks unload, causing small memory leaks
# These leaks adds up and eventually cause issues after generating millions of chunks
# in a single world instance
#
allowPOIUnloading = "default"
# (Default: true) This option workarounds MC-276863, a bug that makes mushrooms appear in non-postprocessed chunks
# This bug is amplified with notickvd as it exposes non-postprocessed chunks to players
#
# This should not affect other worldgen behavior and game mechanics in general
#
suppressGhostMushrooms = "default"
# (Default: true) Whether to synchronize the management of player tickets
#
# In vanilla Minecraft, player tickets are not always removed immediately when players leave an area.
# The delay in removal increases with the chunk systems throughput, but due to vanillas typically
# slow chunk loading, tickets are almost always removed immediately. However, some contraptions rely
# on this immediate removal behavior and tend to be broken with the increased chunk throughput.
# Enabling this option synchronizes player ticket handling, making it more predictable and
# thus improving compatibility with these contraptions.
#
syncPlayerTickets = "default"
# (Default: true) Whether to turn fluid postprocessing into scheduled tick
#
# Fluid post-processing is very expensive when loading in new chunks, and this can affect
# MSPT significantly. This option delays fluid post-processing to scheduled tick to hopefully
# mitigate this issue.
#
fluidPostProcessingToScheduledTick = "default"
# (Default: false) Whether to enable low memory mode
#
# This will attempt to aggressively unload unneeded chunks, saving memory at the cost of additional
# overhead when generating new chunks.
#
lowMemoryMode = "default"
